Melvin Nieves Ramos (born December 28, 1971) is a Puerto Rican former professional baseball outfielder.

Nieves attended Luis Pales Matos High School in Santa Rosa, Puerto Rico before being signed by the Atlanta Braves in 1988.

He collected his first big league hit off the infamous Anthony Young of the New York Mets in his second career at-bat on September 2.

He started the 1993 season in the Braves system, hitting .278 with 10 home runs in 78 games with the Richmond Braves, before being traded with minor leaguer Vince Moore and Donnie Elliott to the San Diego Padres for Fred McGriff in July of that year.

In 43 games with the Padres' AAA team, the Las Vegas Stars, he hit .308 with seven home runs.

He did hit his first career home run that season, a solo shot off pitcher Chris Hammond on September 8.

On March 22, 1996, just before the beginning of the season, Nieves was traded with Raul Casanova and Richie Lewis to the Detroit Tigers for Sean Bergman, Todd Steverson and Cade Gaspar, a minor leaguer.

Perhaps the most memorable game of his 1996 season was on April 6-against the Oakland Athletics, he collected two doubles, a triple and a home run.

Twice in 1996 he also accomplished the fairly rare feat of hitting home runs from both sides of the plate in a game.

The first time he did it was against the Milwaukee Brewers on July 15-he victimized pitchers Ricky Bones and Mike Potts in that game.

Although he hit 20 home runs in 1997 for Detroit, his batting average again was subpar at .228, and he struck out 157 times in 359 at-bats.

He finished his big league career on a ten at-bat long hitless streak.
